7. Subjects with any severe and/or uncontrolled illness.

• Cancer-related symptoms and treatment:

1. Received systemic antineoplastic therapy such as radical surgery, chemotherapy, radical radiotherapy or immunotherapy, biological therapy or participated in Clinical trials of other interventional antineoplastic drugs within 4 weeks before the initiation of study treatment.

2. Prior therapy against the Claudin18.2 target, such as Claudin18.2 monoclonal antibodies, bispecific antibody, ADC, or chimeric antigen receptor T-cell immunotherapy (CAR-T).

3. Tumour has invaded important blood vessels on imaging (Computed Tomography (CT) or Magnetic Resonance Imaging(MRI)) or judged by the investigator to be highly likely to invade important blood vessels during the follow-up study.

4. Poorly controlled pleural, pericardial or peritoneal effusion requiring repeated drainage, judged by the investigator to be unsuitable for enrollment.

5. Subjects with known active central nervous system metastases and/or meningeal metastases or spinal cord compression.

• Study treatment-related:

1. A history of vaccination with the live attenuated vaccine within 28 days before initiation of study treatment or a planned vaccination with live attenuated vaccine during the study.

2. The subject has a history of severe hypersensitivity after previous exposure to a humanized monoclonal antibody or acute or delayed hypersensitivity or intolerance to known components of TQB2103.

3. Requiring systemic therapy within 2 years before initiation of study treatment.

• Subjects with concomitant diseases that seriously endanger the safety of the subjects or affect the completion of the study, or subjects who are considered to be unsuitable for enrollment for other reasons, according to the judgment of the investigators.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose limiting toxicity (DLT)	DLT was defined as toxicities that meet pre-defined severity criteria according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0, and assessed as having suspected relationship to investigational drug that occurred within the first treatment cycle (21 days).	During the first treatment cycle (21 days).
Primary	Maximum tolerated dose (MTD)	MTD was defined as the highest dose at which dose limiting toxicity (DLT) occurred in less than 33% of patients.	During the first treatment cycle (21 days).
Primary	Recommended Phase II Dose (RP2D)	The RP2D of anticancer agents is determined traditionally by dose-limiting toxicities. Nontoxicity or biological endpoints such as pharmacokinetics, pharmacodynamics, and efficacy can also be used to identify RP2D.	During the first treatment cycle (21 days).
Secondary	The area under the curve (AUC)	The area under the curve (AUC) of serum or plasma concentration of ADC drug, total antibody, and small molecule toxin.	2 hours pre-dose, 0, 2, 4, 7, 24, 72, 144, 312, 504 hours (when necessary) after dose on cycle 1 and cycle 3; 2 hours pre-dose, 0 hour, 504 hours (when necessary) after dose on cycle 2, cycle 4, cycle 6, cycle 8.
